If four transmit beams are to be reported, multiple beam pairs may beselected from the result, and the selected beam pairs and thecorresponding measurement result may be reported.

As illustrated in FIG. 4, the network device may send downlink signalsto the terminal device through the transmit beam B1, transmit beam B2and transmit beam B3 of the sending node 1, and may send downlinksignals to the terminal device through the transmit beam B4, transmitbeam B5 and transmit beam B6 of the sending node 2.

For example, the measurement report may be illustrated as follows.Assume that the measurement result is RSRP, and beam pairs which are notlisted may be considered to have particularly low signal strength andmay be ignored.

[B1 b1-1] −60 dB [B1 b1-2] −120 dB [B2 b1-1] −70 dB [B2 b1-2] −120 dB[B3 b1-1] −100 dB [B3 b1-2] −120 dB [B4 b2-1] −120 dB [B4 b2-2] −100 dB[B5 b2-1] −120 dB [B5 b2-2] −65 dB [B6 b2-1] −120 dB [B6 b2-2] −75 dB

If four transmit beams are to be reported, multiple beam pairs may beselected from the result, and the selected beam pairs and thecorresponding measurement result may be reported.

Beam pairs [B1 b1-1], [B2 b1-1], [B5 b2-2] and [B6 b2-2] correspond tooptimal signal quality, and then the four beam pairs may be reported. Inthe reporting process, a receive beam group identifier corresponding toeach receive beam may be reported. That is, a reporting manner for themeasurement result may be illustrated as follows.

[B1 b1]-60 dB

[B2 b1]-70 dB

[B5 b2]-65 dB

[B6 b2]-75 dB

The number of the receive beams or receive beam groups adopted in thesignal measurement process may be different from the number of thereceive beams or receive beam groups reported in the measurement report.

For example, when it is found in the signal measurement process thatquality of signals between one or more receive beams or one or morereceive beam groups and any transmit beam does not meet a reportingcondition, the number of the receive beams or receive beam groupsadopted in the signal measurement process is greater than the number ofthe receive beams or receive beam groups reported in the measurementreport.
